Description

An erect to spreading shrub to 2.5 m high with hairy young branches. Leaves are well separated on mature stems, linear, 1 - 3 cm long, 1 - 1.8 mm wide, usually flat, with recurved margins. They are sparsely hairy when immature, and hairless when mature. Flowers are yellow, pendant to drooping on a stalk to 12 mm long. Flowering typically occurs from November to March. the species is similar to <I>P. bargoensis</I>, which is found in the southern part of the Cumberland Plain and nearer Southern Highlands.

Distribution

Restricted to the Cumberland Plain in western Sydney, between Richmond in the north and Macquarie Fields in the south. The species has a disjunct distribution, with the majority of populations (and 99% of individuals) occurring in the north of the species range in the Agnes Banks, Londonderry, Castlereagh, Berkshire Park and Windsor Downs areas. Core distribution occurs within the Penrith, and to a lesser extent Hawkesbury, local government areas, with isolated and relatively small populations also occurring in the Liverpool, Campbelltown, Bankstown and Blacktown local government areas. The southern and northern populations have distinct habitat differences.

Habitat and ecology

  • Northern populations are confined to aeolian and alluvial sediments and occur in a range of sclerophyll forest and woodland vegetation communities, with the majority of individuals occurring within Agnes Banks Woodland or Castlereagh Scribbly Gum Woodland and some in Cooks River / Castlereagh Ironbark Forests. Southern populations also occupy tertiary alluvium, but extend onto shale sandstone transition communities and into Cooks River / Castlereagh Ironbark Forest.
  • Peak flowering is from November to March with sporadic flowering all year round.
  • An obligate seed regenerator. Seed germination is promoted by fire and also by physical disturbance. Although listed as a short-lived species much of the ecology is poorly known. Maturity is expected in about 10 years.
  • Plants appear to set abundant fruit. Seed is likely to be dispersed, after consumption of the fruit, by large birds such as currawongs and large mammals such as wallabies, kangaroos and possums.
  • Abundance at a site appears to be related to disturbance history. Sites with higher abundance also appear to be more disturbed.
